CONSTRUCTION OF BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 346,638, dated August3, 1886. Application filed March 13, 1886. Serial No. 196,294/ (Nomodel.)

To all whom, it may concern:

Be it known that I, SAMUEL GrRUs BURRIS, of Victoria, in the ProvinceofBritish Oolumbia, and Dominion of Canada, have invented a new and usefulImprovement in the Con struction of Buildings, of which the following isa specification, reference being had to the annexed drawings, forming apart thereof, in which Figure 1 is an isometrical view of a part of abuilding constructed according to my improvement, with angle broken awayto show construction at intersections of walls, floors, &c. Fig. 2 is atransverse section of a portion of a slightly modified form of the roof,ceiling, and wall. Fig. 3 is a section showing solid roof with plate andventilators same as walls, &c. Fig. 4 is a transverse section of aceiling formed on ordinary joists. Fig. 5 is a side view of floors andjoists. Fig. 6 is an end view of the floor and joists. Fig. 7 is ahorizontal section of a solid wall made accord ing to my improvement.

Similar letters of reference indicate corresponding parts in thedifferent figures of the drawings.

My invention relates to the class of buildings made of wood; and itconsists of a wall, ceiling, floor, and roof, built solidly oflongitudinally-grooved timbers, or of studs, joists, and rafters withlongitudinally-grooved strips or timbers attached thereto, and in curvedgrooves or coves formed in the face of the grooved timbers or strips forreceiving and retaining the mortar or cement with which the timbers arecoated.

In carrying out my invention I form the principal parts of the buildingof timbers A, grooved longitudinally on opposite edges at shortintervals, leaving projecting tongues a, for receiving the mortar orcement B, with which the inner or outer surface of the wall is coated.To secure a still firmer attachment of the mortar to the wall or ceilingformed of the timbers A,I produce in the timbers,by the aid of suitablemachinery, circular undercut grooves or coves b, which traverse thelongitudinal grooves of the timbers, and form in the tongues aoverhanging books or ledges, into which the mortar is pressed whenapplied to the timbers.

The expansion and contraction of the wood by the absorption ofmoistureis counteracted by parallel grooves dividing the edges oftimbers into a number of tongues which contract and expand inthemselves, thus forming a yielding surface to the wall that willprevent cracking of the plaster.

Along the center of each plain face of each timber A, I form asemicircular groove, c,the grooves of the adjacent timbers,when arrangedagainst each other, as shown in the several figures of the drawings,forming ventilatingpassages, which extend throughout the entire lengthof the timbers, and communicate at the ends of the timbers with anothergroove worked in plate or bond timber, which communicates with the openair at angles or other convenient places.-

In Fig. 6 l have shown the vertical timbers A capped by a plate or bondtimber, O,in the upper and lower sides of which are formed grooves d,which communicate with the ventilating-passages of the timbers on whichthe plate rests, and of those resting on the plate.

When the timbers A are employed for the construction of a floor,as shownin Figs.5 and 6,the grooves are made only in the lower side, which formsthe ceiling in the room below, the upper edges of the timbers beingplaned smooth to form the floor. In this case no flooring-boards will berequired. Where it is preferred to construct the floor with joists andwith flooringboards, grooved strips or timbers A are attached by theirplain sides to the joists D, Fig. 4.

The construction of roofs is substantially the same as that of floorsand ceilings, the timbers A being secured together to form the body ofthe roof, as shown in Fig. 3, with the grooved surface uppermost, theroof being covered with a suitable cement, which is retained in place bythe undercut groovesb and tongues a of the timbers.

W hen desirable,a roof may be constructed of rafters E, with strips Aapplied thereto with their grooved surfaces uppermost. The cementforming the outersurface ofthe roofis then applied to the strips A, andis held by the circular undercut grooves Z) and tongues c.

A building constructed according to my improvement is practically fire,weather, and

vermin proof. The incombustible cement, which is applied to the exteriorand interior surfaces of the building,prevents the combustion of thewood inclosed thereby. The cement being anon-conductorofheat-,andwater-proof, excludes cold and moisture, and as there are nospaces for vermin to lodge in the walls my improvement renders abuilding free from the objectionsnrged against buildings having ho1- 10wwalls.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A wall, floor, ceiling, or roof formed of series of timbers A,grooved longitudinally on one or more of their edges, and provided inopposite sides thereof with grooves forming ventilating-passages,substantially as herein shown and described.

2. A timber for constructing wals, floors, ceilings, or roofs, havingformed upon one or more of its sides longitudinal and transverse groovesfor retaining mortar or cement, and having in'one or more of its sides agroove forming with the adjacent timber a ventilatingpassage,substantially as herein shown and described.

3. A wall formed of timbers A, having in one or both edges longitudinalgrooves and transverse undercut grooves, provided in opposite andadjacent sides with ventilatinggrooves c, and a coat, B, of cement ormortar applied to the grooved surface of the timbers, substantially asherein shown and described.

4. A wall formed of vertical timbers A,having grooved edges, andprovided with ventilating-grooves c, and one or more plates, 0, groovedin opposite edges, and having in opposite sides ventilating-grooves d,substantially as herein shown and described.
